Do you think that the X and Y legendaries could be based off on Norse Mythology? Look at the deer lookalike, the eagle lookalike, for the two realms. The third realm the underworld is a snake. MAybe Z = serpentine?

I feel I should make a general statement that my answer to any question of this kind about X and Y is going to be along the lines of “eh, whatever.”

I guess Yveltal, with the initial vocalic Y, does kinda sound like it could be Germanic or Nordic, but Xerneas doesn’t – I mean, I don’t really know anything about that language family but I’m not sure they even have an X sound, let alone words with an initial X.  Honestly it feels like a Greek name to me.  Also I just don’t think Yveltal looks like an eagle.  Something in the shape of the head, and the feathery collar, just screams ‘vulture’ to me.

EDIT: Another reader adds the following:

“There aren’t two realms in Norse mythology what? There is an eagle on the world tree, but there were actually four deer and also a dragon and a raven. It’s likely not Norse-related just because there’s a deer and an eagle.”

I think the first person was referring to the old division of the universe into heaven, earth and the underworld, which is common across many cultures, although from what I recall of Norse mythology, they actually had *several* realms, including two heavens, at least two underworlds, and possibly more than one earth… although I’m very much a Greco-Roman fellow and it has been a long time since I read anything on the subject.

Also I’m sure I remember something about a squirrel that used to carry insults up and down the World Tree between the eagle and Nidhogg…
